## AI overview

A coding challenge asks readers to build a command-line benchmarking tool modeled on hyperfine. The tool should run commands repeatedly, measure execution time and variation, compare commands, export results, and warn about unreliable measurements.

## Source excerpt

This challenge is to build your own benchmarking tool.
